Electrically wiring parts mounted on an engine

Abstract

An electrically wiring arrangement mounted on the upper portion of a gasoline engine in an automobile or the like in which the current receiving connectors can be readily engaged with the current supplying connectors of a wire harness. Mounting parts, namely, ignition coils, are mounted above the cylinders, respectively, forming the upper portion of an engine body with screws. Each ignition coil has a current receiving connector on top which has contact terminals extending upright. An igniter having an external current receiving connector is mounted on the inner surface of one end portion of the cylinder head cover, and current supplying terminals, each of which has a connector housing in which female metal terminals are disposed, are mounted on the same inner surface of the cylinder head cover in such a manner that they are in alignment with the contact terminals of the ignition coils. The female metal terminals are connected to the igniter through conductors arranged in a predetermined circuit pattern.

What is claimed is: 
     
       1. An electrical wiring device for distributing a signal through a wire harness to at least one of an ignition coil and an injector mounted on an upper portion of an engine via a current receiving device on each of said at least one ignition coil and injector, said wiring device comprising: a current supplying connector associated with each of said at least one ignition coil and injector for supplying said signal, via said current receiving device, to said at least one ignition coil and injector, said current supplying connector being integrally formed on the inner surface of a cylinder head cover in such a manner that said current supplying connector electrically interfaces with said current receiving device when said cover is installed; and   a current supplying circuit, electrically connected to said current supplying connector, for supplying said signal to said current supplying connector.   
     
     
       2. An electrical wiring device as claimed in claim 1, wherein said current supplying device has a current supplying unit for each of said one injector and connector. 
     
     
       3. An electrically wiring device as claimed in claim 1, wherein said current supplying device, said current supplying circuit and said current receiving connector are integrally provided on said cylinder head cover. 
     
     
       4. An electrical wiring device for an internal combustion engine, for distribution of electrical currents through a wire harness to at least one of an ignition coil and an electrical injector both of which are mounted on an upper portion of said internal combustion engine and wherein each of said ignition coil and electrical injector are equipped with current receiving devices and; said electrical wiring device is integrally formed on an inner surface of a cylinder head cover in such a manner that when said cylinder head cover is installed, it provides an electrical interface between at least one of said ignition coil and electrical injector current receiving devices, and at least one of several current supplying devices integral to said electrical wiring device and;   a current supplying circuit for supplying said electrical currents to said electrical wiring device is provided with a first connector interfacing with and supplying current to a corresponding second connector on said electrical wiring device and;   further wherein said current supplying devices integral to said cylinder head cover electrical wiring device are so designed as to interface and be compatible with said current receiving devices with which said ignition coils and electrical injectors are equipped.
